HPG-I
Product: HPG
Chemical Name: Hydroxypropyl guar
CAS Number: 39421-75-5
Applications
As a nonionic polymeric viscosifier derived from natural Guar bean, HPG-I is of
suitable substitution level, good aqua-dissolvability / dispersibility, and high
compatibility with anionic, cationic and nonionic surfactant. With its good
electrolyte tolerance, viscosity stability and good shear dilutability, HPG-I
can be used in fracture fluids and drilling mud in oil field industry.
Fracture fluids are for the purpose to improve drill productivity and made by
mixing HPG-I with water, cross-linker, polymerizing agent, and proppant. The
normal level of use in fracture fluids is 0.3-0.5% by weight.
HPG-I polymer can also be used in low-solids drilling fluids as a viscosifier
and fluid-loss additive. It will develop viscosity in both water and brine.
